Dirty birds flyin' out the coupe like a pigeon

Meaning
Great use of wordplay here!
Basically he has alot dirty, sexy women getting out his 2 door car.
However..
Note the simile on Dirty birds and pigeons. Feral Pigeons are perceived as some of the most unhygienic animals that live in human habitats. Also the obvious — they fly.

Note the homophone on coupe;
- A Coupe is typically a 2 door car. Often sports cars are Coupes.

- A Coop is usually known as cage for keeping chickens in but also applies to pigeons when kept as pets.
